What conditions can affect the timing of menopause?

Certain medical and surgical conditions can influence the timing of Menopause.

Surgical removal of the ovaries

The surgical removal of the ovaries (Oophorectomy) in an ovulating woman will result in an immediate menopause, sometimes termed a surgical menopause. In this case, there is no peri-menopause, and after surgery, a woman will generally experience the signs and symptoms of menopause. In cases of surgical menopause, women often report that the abrupt onset of menopausal symptoms results in particularly severe symptoms, but this is not always the case.

The ovaries are often removed together with the removal of the uterus. If a hysterectomy is performed without removal of both ovaries in a woman who has not yet reached menopause, the remaining ovary or ovaries are still capable of normal hormone production. While a woman cannot menstruate after the uterus is removed by a hysterectomy, the ovaries themselves can continue to produce hormones up until the normal time when menopause would naturally occur. At this time a woman could experience the other symptoms of menopause like hot flushes and mood swings. These symptoms would then not be associated with the cessation of menstruation. Another possibility is that ovarian failure will occur earlier than the expected time of menopause, as early as 1-2 years following the hysterectomy. If this happens, a woman may or may not experience symptoms of menopause.

Cancer chemotherapy and radiation therapy

Depending upon the type and location of the cancer and its treatment, these types of cancer therapy can result in menopause if given to an ovulating woman. In this case, the symptoms of menopause may begin during the cancer treatment or may develop in the months following the treatment.

Premature ovarian failure

Premature ovarian failure is defined as the occurrence of menopause before the age of 40. This condition occurs in about 1% of all women. The cause of premature ovarian failure is not fully understood, but it may be related to Autoimmune Diseases or inherited (genetic) factors.
